operations

Question 1

Multiplier

Answer 1

a number that multiplies another number (multiplicand)

multiplicand × multiplier = product

Question 2

Numerator

Answer 2

the top term of a fraction

Example: In 1/10 the numerator is 1

Question 3

Improper fraction

Answer 3

A fraction where the numerator is larger than the denominator

Example: 3/2

Question 4

Denominator

Answer 4

the bottom term of a fraction

Example: In 1/10 the denominator is 10

Question 5

Dividend

Answer 5

A number that is divided by another number (divisor) to find the quotient

Example: dividend ÷ divisor = quotient

Question 6

Quotient

Answer 6

the result of dividing two numbers

Example: dividend ÷ divisor = quotient

Question 7

Percentages

Answer 7

A way to represent part-to-whole relationships, where the percent is the part out of 100.

Example: One half: 50% = 1/2 = 0.50

Question 8

Greatest Common Factor (GCF) / Greatest Common Divisor (GCD)

Answer 8

the greatest factor that is common to two or more numbers; the largest number that will divide evenly into two or more numbers

Example:
For 12 and 15, GCF = 3
Factors of 12: 1, 2, 3, 4, 6, 12
Factors of 15: 1, 3, 5, 15

Question 9

Factors

Answer 9

Values that are multiplied to get another number.

Example: Some factors of 12 are 3 and 4 because 3×4=12

Question 10

Least Common Multiple (LCM)

Answer 10

the smallest number that is a multiple of two or more numbers; the smallest number two or more numbers will divide into evenly

Example:
For 12 and 15, LCM = 60
Multiples of 12: 12, 24, 36, 48, 60
Multiples of 15: 15, 30, 45, 60

Question 11

Distributive Property

Answer 11

a number in front of a group of terms will multiply all terms in the grouping individually

“they can distribute themselves”

Example: a(b+c)=ab+ac

Question 12

Fractions

Answer 12

usually represent partial numbers

Example: One half: 50% = 1/2 = 0.50

Question 13

Difference

Answer 13

the result of subtracting one number from another

Example: x−y=difference

Question 14

Associative Property

Answer 14

An operation is associative if regrouping the terms does not change the outcome

“they can associate with whomever they choose”

Example: (a+b)+c=a+(b+c)

Question 15

Product

Answer 15

the result of multiplying two or more numbers

Example: multiplicand × multiplier = product

Question 16

Divisor

Answer 16

A number that divides another number (dividend) to find the quotient

Example: dividend ÷ divisor = quotient

Question 17

Commutative Property

Answer 17

An operation is commutative if changing the order of terms does not change the outcome

“they can commute around”

Example: a+b=b+a

Question 18

Common Denominator

Answer 18

when 2 fractions share the same total parts of whatever item or items are being represented

Example: 1/3 and 2/3

Question 19

Mixed number

Answer 19

A whole number with a fraction

Example: 3 1/2

Question 20

Reciprocal Fraction

Answer 20

The inverse or “flip” of a fraction where the top and bottom number switch places

Example: 1/2 -> 2/1 3/5 -> 5/3

Question 21

Order of Operations

Answer 21

PEMDAS: the set order in which multi-step equations must be solved: Parenthesis, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right)

Question 22

Decimal

Answer 22

Numbers less than 1 displayed using place values and the powers of ten

Example: 0.024

Question 23

Addend

Answer 23

number that is added to another number

Example: addend + addend = sum

Question 24

Decimal Fractions

Answer 24

fractions with a denominator of 10

Example: 1/10 =0.1

Question 25

Real numbers

Answer 25

numbers that have a specific value

Example: -2, 3, 1/2, 3.2, √2

Question 26

Multiplicand

Answer 26

a number that is multiplied by another number (multiplier)

Example: multiplicand × multiplier = product

Question 27

Sum

Answer 27

the result of adding two or more numbers, a total

Example: addend + addend = sum
